I recently installed a Shadin on my PushPull (for those of you soon off the the Bahamas, get used to that name). But recently had all of the fuel leak out of my left wing due to a leaking gasket, and it did not register on the Shadin obviously, but did show on the fuel guage. Likewise it would have made no difference to know how much I burned per average house, nor how much was in the tank when I departed. As such, and while those other ideas are good, as is the Shadin, it is still worth it to try and get the fuel guages calibrated and operational.
